What happened

Shares ofSprouts Farmers Market Inc. (NASDAQ: SFM) were getting sold off Wednesday after the organic grocer lowered its guidance for the current quarter and full year. As of 12:40 p.m. EDT, the stock was down 13.6%.

So what

Ahead of its participation in the Global Retailing Conference Thursday, Sprouts dumped the bad news today, blaming its newly weakened outlook on ongoing food price deflation and an increased promotional environment.

The company now foresees flat comparable-sales growth for the current quarter, with a growth forecast in the1.5% to 2.5% range for the full year, down from the 3.5% to 4.5% range it gave previously, and earnings per share of $0.83 to $0.86, down from the previous range of $0.96 to $0.98.

Separately, the company authorized a $250 million share buyback program; it completed its prior share buyback program in July. Repurchasing shares is common tactic for companies that believe their stock is undervalued. The new authorization is worth about 8% of the company's total market value.

Now what

The market's reaction is unsurprising after such a sharp guidance cut, as the current EPS range now signals a slight decline in profits for the year. While peers likeWhole Foodsand Fresh Market struggled in recent quarters, Sprouts had outperformed the industry. Now, that appears to be changing. It's unclear if this reflects an industrywide shift, or something that's only afflicting Sprouts.

The market, however, seems to believe it's an segment-wide problem, as Whole Foods shares fell as well, down 5.7%, and Kroger dropped 4.7% as of 12:40 p.m. Expect Sprouts to elaborate on its predicament Thursday at the Goldman Sachs conference, but for now it's hard to spin this news any other way but negative.
